Lexeo Therapeutics, Inc. LXEO

We are a clinical stage genetic medicine company dedicated to reshaping heart health by applying pioneering science to fundamentally change how cardiovascular diseases are treated. We are advancing a portfolio of therapeutic candidates that take aim at the underlying genetic causes of conditions, including Friedreich ataxia, or FA, cardiomyopathy, plakophilin-2, or PKP2, arrhythmogenic cardiomyopathy, and other devastating diseases with high unmet need.

Our most advanced cardiovascular product candidate, LX2006 for the treatment of FA cardiomyopathy, is currently being evaluated in SUNRISE-FA, our ongoing Phase 1/2 clinical trial and in a Cornell investigator-initiated trial. In October 2025, we reported positive interim clinical data demonstrating an encouraging safety profile and evidence of meaningful cardiac and functional benefit. Further, interim clinical data presented in a late-breaker presentation at the American College of Cardiology (ACC) Annual Meeting in March 2026 continue to show sustained or deepening improvements across both cardiac and neurologic measures of FA. In February 2026, we submitted the final registrational trial design and statistical analysis plan for the SUNRISE-FA 2 study to the U.S. Food and Drug Administration (FDA) following a Type B meeting. We expect to receive final feedback from the FDA in the second quarter of 2026 and plan to initiate a registrational study in the first half of 2026.
